Improved Standard-Model prediction for K L → ℓ + ℓ −

Journal of High Energy Physics
We present a comprehensive calculation of the K L → γ ∗ γ ∗ form factor in dispersion theory, using input from the leptonic decays K L → ℓ + ℓ − γ, $${K}_{L}\to {{\ell}}_{1}^{+}{{\ell}}_{1}^{-}{{\ell}}_{2}^{+}{{\ell}}_{2}^{-}$$ , the hadronic mode K L ...

FCNC charmed-hadron decays with invisible singlet particles in light of recent data

Journal of High Energy Physics, 2023
The flavor-changing neutral current (FCNC) decays of charmed hadrons with missing energy (Ɇ) can serve as potentially promising hunting grounds for hints of new physics, as the standard-model backgrounds are very suppressed.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Uniting low-energy semileptonic and hadronic anomalies within SMEFT

Journal of High Energy Physics
Two categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes only to processes of the same category.

Naturally astrophobic QCD axion

Journal of High Energy Physics, 2023
We present a QCD axion model where the couplings of the axion to nucleons, electrons, and muons are naturally suppressed because of the appropriate choice of the Peccei-Quinn charges of the Standard Model fermions.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Inclusive B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\ell}^{+}{\ell}^{-} $$ at the LHC: theory predictions and new-physics reach

Journal of High Energy Physics
We present theoretical predictions for observables in inclusive B ¯ → X s ℓ + ℓ − $$ \overline{B}\to {X}_s{\ell}^{+}{\ell}^{-} $$ suitable for measurements at hadron colliders through a sum-over-exclusive approach.

Impact of indirect CP violation on Br(K S → μ + μ − ) ℓ=0

Journal of High Energy Physics, 2023
The decay K S → (μ + μ − ) ℓ=0, with the final muon pair in an angular-momentum zero state, is a sensitive probe of short-distance physics. It has recently been shown how to extract this branching ratio from neutral kaon decay data. We point out that the

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

Molecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Investigating non-local contributions in B s → ϕ ℓ ¯ ℓ $$ {B}_s\to \phi \overline{\ell}\ell $$ including higher-twist effects

Journal of High Energy Physics
We analyze the impact of higher-twist three-particle B s -meson light-cone distribution amplitudes (LCDAs) on the non-local form factors for the B s → ϕ ℓ ¯ ℓ $$ {B}_s\to \phi \overline{\ell}\ell $$ transition focusing on the ‘charm-loop’ contribution ...
